Radish Growing and Care Guide

Select a site with full sun, although partial shade is tolerable in hot areas. Work compost and optional balanced, low-nitrogen organic fertilizer into the top 6 inches of sandy to loamy soil with a neutral pH (6 to 7). Ensure soil is loose and well-draining to prevent compaction around the roots.

Sow seeds directly into the ground or containers. For containers, ensure a depth of at least 5 inches for short varieties and deeper pots for daikon. Plant seeds 1/2 inch deep and 1 to 2 inches apart, with rows spaced 10 to 12 inches apart.

Water the soil regularly to keep it consistently moist, providing approximately 1 inch of water per week. Pull any weeds as soon as they appear to reduce competition for nutrients.

Monitor seedlings for germination, which typically occurs in 5 to 10 days. Once seedlings reach approximately 2 inches in height, thin them out so that plants are spaced 3 inches apart.

Continue regular watering to prevent the roots from becoming woody or pithy and to prevent premature bolting. Consider using mulch to retain soil moisture.

Harvest when roots reach the mature size for the specific variety, the 'shoulders' of the root press against the soil surface, and leaves are 6 to 8 inches high. Grasp leaves at the base and pull with a gentle twisting motion. Use a trowel to loosen soil around long, tapering varieties like daikon to avoid breakage.
